Constant 30% CPU Usage In Windows 7 When Idle
Aug 31, 2012
I'm having a problem where windows utilizes 30% of CPU usage even when Idle.The problem starts when i open a program like games or any intensive application that requires alot of CPU load. But after closing the program, i noticed in my taskbar that windows generates and continues to use up to 30% of CPU load on other applications for example Dwm.exe (desktop windows management) but if i stop DWN.exe from taskbar, another program or service will replace it and generates the same CPU load, if i stop that another will take its place like svchost or the taskbar.exe itself getting a 25 to 27 cpu load. Its like an ongoing cycle or Loop of CPU usage, its supposed to stop after closing programs.I already have done steps i thought would clear this problem and these are:
Registry fix
ran Avast Anti-virus
reset BIOS
ran anti malware programs
ran Msconfig and disabled unwanted programs running on the background
ran windows 7 update
updated all my drivers
Summary:The problem still persist. This problem doesnt occur after boot, everything is fine with my system idle getting 97%. it only starts after i ran a program that utilizes high CPU load but after closing it, the heavy CPU load continues by replacing the closed program with another either dwm.exe,taskmanager.exe,svchost.exe..etc

My Win 7 (64 bit) computer with a Intel i5 760 CPU, 4Gb of ram and AT Radeon HD 7500 Graphics card has developed a problem with about 25% constant CPU activity and constant disc activity. Task Manager shows that this is due to the "NT Kernel and System" process, and it can't be stopped. The surprising thing is that I get exactly the same problem in Safe Mode with no connection to the Network, so what the heck is going on?

My Win 7 Acer RAM (3GB) is running at 46% idle? This seems to be alot?
Though it does not increase that much with windows open, even when I open WMP and play music it only goes up to 49-50%.
I use the gadget on screen and double check it with task manager, they are the same.
This is more than the previous Vista Basic machine, which I returned, it ran at 40%?
Is there a way to adjust or sort this?
Oh, this morning it went up 99% and I could not switch it off, I had to hold the button to switch off?

I have a program that measures bandwidth and its reporting that I am downloading at full speed (1.2 mb/s ) all the time, and I think its accurate as my internet feels really slow. I double checked I wasn't downloading anything, and that all of the updates were on idle, but there is still traffic. What should I do? Also, I noticed a ridiculous drop from 250 GB to 217 GB of free space. The free space drop is gone, its showing 250 GB but the bandwidth is still a problem

For some reason I have 2GB (out of 4GB) of RAM being and my laptop is slow in general. Even typing this it's lagging.
I take it this could be a virus?

I recently reformatted my computer for this issue but it did not seem to help. Right after I turn my computer on, and my few programs boot up, my computer sits at 1.35 Gb of ram usage. After playing even a single game it jumps to about 1.60 Idle. The only programs I have turned on are Steam, EVGA Precision and nvidia control panel,etc. Here is a list of the processes I have running, where are they coming from and is something wrong where it's taking up this much memory?I was also dealing with a problem of my CPU using 25% for system interrupts after waking up from sleep, I noticed a lot of errors/warnings in the event log, I'm wondering if these could have something to do with it.Only the ones for AUG 29th are since I turned on my PC today (and didn't let it go to sleep)

Just today I decided to update my IE8 to IE9 (Win 7). There was also an unknown windows update to install (today 15th Jan 12)). As soon as it was installed (without even opening IE) my system is now using 25% more ram (about 700 of 1G compared to around 500 before). I uninstalled IE9 and went back to 8 as shown on the microsoft page, but as soon as i start windows its using 700 again. I tried rolling back to an earlier point today and still have super high ram usage. Now with just this single IE tab open im using 900!

I have win 7 64 bit and have noticed that once my PC is active for more than a few days, the idle memory usage goes up dramatically. See pic, even with only idle processes, i am using 49% of 4gb ram. When i resart my PC, idle memory usage goes down to around 25%, which is a much more sane number. I've tried using a memory cleaning program called "CleanMem", but it doesn't seem to do anything.....

My issue is that my fan runs very loudly and does not turn off during idle/slow periods. I downloaded the speedfan program and this is how it looks currently. [URL]I don't think the difference between idle and running Chrome + Steam in the background would be enough to matter, so i'm not in a completely idle mode now. This is essentially my constant setup.I'm rather inept when it comes to these things so i'm really not sure if this is even a problem or not. I know that cpu fans are always running, but i can't imagine 2800-2900 rpm being an idle speed. My temperatures are stable(as far as i know) and they only get to about 45% during heavier cpu usage. I cleaned out the dust in the system, but i think i may have missed the heatsink or whatever itself.I have also heard that doing a disk cleanup and defragmentation can solve the issue of a fan running constantly, however, doing that did not seem to help.

I recently installed some new hardware into my computer.
Specs:
Gigabyte Z68XP-UD4
i5 2500k @ 4.5GHz
HyperX DDR3 1600
2x HD5870s
PC P&C 750W PSU
Crucial M4 64GB SSD (for my OS)
Everything went fine, computer performs top notch. But I'm having several issues (note, these issues happened BEFORE the CPU overclock also, so that isn't the problem).
1. Randomly (doesn't happen often), my computer will seem to lose internet connection. I'm hard wired right to my Linksys E3000, and it says that I'm connected, but no internet sites will load. Also, I cannot open the "network and sharing center". It just won't let me click on the icon in the task bar. And my CPU usage hovers around 25-30% when this happens. I downloaded and installed Process Explorer to see what the culprit was, and I noticed that of the 30% CPU usage, "System Idle Process" was taking up 75% of said CPU usage. It doesn't happen often at all, and restarting clears the problem up. But even though this SSD is lightning fast.
2. Smaller problem, but sometimes when I want to shutdown or restart, my computer just wont. It will sit at the "shutting down" screen forever and will basically do nothing, like there is a process in the background preventing it from doing its thing.

I have had my laptop for around a year now, and it's always been pretty fast for a cheapish laptop, It's an advent modena m100 in blue, but recently it has started getting real slow, like my CPU Usage is at 100% all the time and my Physical memory usage is running quite high aswell, without even having any programs open.

When I first boot up the machine and start using it (win 7 ultimate 64bit) the memory usage stays arround 40%. If I keep using it, the memory usage will slowly increase until it reaches 99%. If I boot up the machine and just leave it there for a couple of hours, the same happens.I try to restart (via windows), it logs off, shuts down the system, the coolers keep spinning, the motherboard lights are still on, but it doesn't boot up again. It remains like that. I have to restart via reset button or power button.

I have 7, 64 bit, running on an HP and have been keeping pretty up to date on my drivers.amd a4 3300 processor with graphics card, and 4 g ram.When trying to use menus, the window or entire screen will seem as though it refreshes, closing the menu, i can watch the bar across the top of windows flash as if it had just disappeared for a split second and the menu is gone, leaving me to reopen it, but at a second or less between these refreshes I have to be quick on the pointer to get to what I want. It seems to happen on any menu item, including all drop downs, wether im right clicking a start menu pined item, a choice dropdown on a webpage, a setting dropdown, etc. it doesnt alwasys do this but more often than not. It seems like I can sometimes restart the pc and it will work, but it often will do it right at startup. I hadnt noticed it til I connected the VGA out AND the HDMI out to the same tv (dont know why I did it at the same time, I think to compare the cropping). Also, I used system restore to go back to before a bunch of updates and it seemed to fix it, but that might just be because the pc restarted in the process.

I am using my iPhone to try to figure out my computer. So it is the only one I have. It is in a constant loop of windows not starting and trying to fix errors then says it can't, I can't get it to load in safe mode or anything else. I can use the box where u put in commands and found my registry hive says 0 bytes. I do not know how to fix this. And I do not have a windows disk cause it came already installed. So how can I fix this and what do I need to do or try.
I do have a Windows 7 product key on the back of my computer.

I recently upgraded my existing PC with a new hard drive (WD 1TB Caviar Black), Windows 7 Ult x64, & upped my mobo to its max of 16 GB DDR3 RAM.I originally had problems after install with some of my partitions & hard drives not showing but everything worked itself out alright.However, now a new problem has cropped up, and I'm not entirely sure if its related to the original issue or if it is a whole new problem.Almost any program that I run will work for a time, but eventually stop responding. When I try to close the program, I will get a message from windows asking if I would like to end the process tree. This happens with everything, from Chrome to the League of Legends installer to Windows Explorer. If I hit yes, nothing will happen except for the "wait" cursor will appear, and my taskbar will completely disappear. It will usually catch up eventually, but I actually had to reset my computer during the LoL install, and Windows would not start up afterwards. I had to reinsert my Windows 7 disk and repair the installation.
Nothing I seem to do can fix this. All drivers are up to date, as are all Windows 7 updates. I upgraded from Windows XP, and tbh, at this point I'm regretting it.My system specs are as follows:[CODE]

I just done a fresh clean install of Windows 7 (due to brand new WD Blue 500Gb HDD) on a PB EasyNote TS-13HR, all drivers are the latest from PB's website all Windows 7 updates done and MS Sec Essentials insatlled.It crashes constantly but can then sometimes it'll be fine for hours I suspect a compatibilty issue with HDD, but not to sure really?Below is the debug from memory.dmp - it seems to point at a registry error, which is new (older crash dumps didn't say that!)

Bit of a weird one here, I recently restored an old Dell Dimension 8250 to run windows 7 pro 32bit. It has 1gb of ram and i've heard its capable enough. The installation went fine and everything worked for a couple of days, but now any non original programs i install appcrash straight away eg. Firefox, daemon tools, utorrent.. Control panel wont let me uninstall them so i have to delete their folders and use control panel to remove them from list. Then i reinstall and it will work until a few restarts of the system.
Also it used to connect to the wireless but now it only sees my nieghbours networks and not mine which is weird as all other laptops in my house can connect fine?

constant boot problems about 70% of the time, and Win 7 launches are dicey. Sometimes the computer freezes while showing the Desktop. If all drivers eventually load successfully, then the computer runs fine after that. The problem is just in getting it up and running initially.Note that I have turned off MS .NET Framework on someone's suggestion, but I continue to experience difficulty booting my computer successful. I have run Dell hardware tests and these have all been A-OK. I'm attaching the results from running the Seven Forums diagnostic tool (including minidump) from crash.

A few days ago I awoke my Toshiba laptop in the morning, only to find it hanging up with continuous HDD activity. After a while I did a hard shutdown and tried to restart, but the HDD activity continued, and after an hour of trying, it was barely past the start screen - zero chance of any useful activity.
It performs normally in command prompt, and I can barely get it booted in safe mode (HDD thrash eventually stops until I ask it to do anything). Task manager doesn't show any unusual processes or services, but the resource monitor does show the HDD activity. Chkdsk (thru command prompt) on the X and D partitions came out fine, but on the C drive it doesn't even get to 1% and slows to about 1 file/minute. I attempted a Start Repair, but it said nothing was wrong. Tried a System Restore, but for some reason no restore points could be found.
The HDD seems to be performing OK (I'm using robocopy/cmd prompt to copy all I can to an external HDD), with only the occasional I/O error. It's possible I caught a virus, although I'm generally cautious (Ad-Aware antivirus, all updates ASAP, regular scans with this and Malwarebytes).
I'd really, really like to find a way out of this without a complete reformat. I've tried stopping everything I could in Safe Mode, but to no avail. Also tried to uninstall my AV software (and anything else that seemed to be running at startup), but was denied there as well.

so this is quite the long explanation. Today i upgraded to an i7 3770k with a asus P8Z77-VLK and a corsair H60 water block. I did not change to touch any other part of my computer. When I went to go boot BIOS posts but then as the windows 7 loading animation starts then about 2 seconds in i get an instant BSOD too fast to read and it restarts. I have tried startup repair, I have tried the windows repair disc, I tried the windows install DVD, I tried system restore(which failed error code 0x800700b7), I ran the memory diagnostic(no problems), I even went into the command prompt and did chkdsk.

For the last couple of weeks (I was just given the laptop) my friends Dell Inspiron has been Blue Screen of Death'ing on start then rebooting (loop on this) - I was able to see the BSOD when I disabled the "reboot on error" and all I get is the following: Blue Screen STOP: 0x0000007B.I cannot get into Safe Mode (same error) to get any dumps (at least I wouldn't know how)I tried Startup Recovery, Last known configuration, Restor points (many of them), Chkdsk, sfc, and bootsec but nothing seems to resolve the problem... The next step is a re-install from the Dell Recovery drive (I hope because I don't have the origial Windows 7 Dell Install CD),

I've been having troubles for a month or two now and decided to finally take my woes to the internet in the hopes someone could help me, before I consider giving up and buying a new laptop.I had troubles first running Windows 7 Home x64, now I'm running Windows 7 Ultimate 32 bit. I have a Sony VAIO laptop, 500 GB hard drive.I first had problems after running a Malwarebytes scan - I ran it overnight and when I woke up my screen was black and said "Operating system not found" or something to that effect. From then on, my computer would only boot about once in every 4 times I tried. I ran startup repair many times, and when I did get in things ran very slowly and inevitably I would get an abrupt BSOD. This persisted for a month or so. Some days it worked great, but always went back to the usual.A few days ago I bought a hard drive enclosure, got all the files off my hard drive, and totally formatted my hard drive. Then, after some difficulties in the installation, I installed Windows 7 Ultimate, 32 bit, because a family member had the disc for it.The computer worked a lot better at first but now again it's running slowly and I'm starting to get the BSOD! Sometimes I can use it 5 minutes before I get the BSOD, sometimes I have 2 hours.It's been hard to write this because it keeps BSODing while I was typing.I set it to not restart when it crashes, so I could write down the error messages I got on the BSOD. The second to last series of numbers is the only thing that changes BSOD-to-BSOD. Here are the codes (I skipped the middle part, which is text and all the same) for the last 4

I recently had a virus on my computer and did a clean install of Windows 7 Ultimate. Now it seems that randomly my processes will stop responding, usually if I have a couple things running at once. I cant seem to burn a DVD because every time it will crash during it. Usually when it happens all the processes wont respong, task manager wont come up and a couple minutes later my system restarts. I have run a memtest and it turned up with no errors.

Can someone explain the Windows Build 7601 program to me.I've asked the guy that built this computer for me and he says it's just from an update I installed update 971033 to be more precise and that I could not get rid of.However he did not offer me the product key the program is requesting or any other fix for that matter.The only problems I'm noticing with it are that I cannot hold a desktop background and the constant popups stating that my Windows 7 may not be genuine or may be counterfeit.
